Video: Windows Subsystem for Linux and Golang Environment with Visual Studio Code

Recently I have been playing with Golang and I found that there few packages that do not work with windows. So for that most of people are using VirtualBox and then installing Linux on that But Actually, you don’t need to do that as now you already have windows Linux subsystem which provides you a complete Linux Environment in your windows environment itself.

To educate, this I have created a video for the same. You can find that video below.



Here in this video, You can see that I have installed Ubuntu Linux subsystem.

What is Linux Subsystem:

Windows Linux Subsystem is a compatibility layer developed by Microsoft and Linux distributions for running Linux Environment natively on Windows 10. It was introduced with the Anniversary update.

From the following links, you can find more about it.
https://en.wikipedia.org/wiki/Windows_Subsystem_for_Linux

Tree shakeable providers/services in Angular 6

Recently before some time Angular 6 was released and there are a couple of features that are added with Angular 6. In this blog post series, we are going to learn all these new features one by one. Today this post is all about Tree Shakeable providers in Angular 6 which is a new recommended way to create a new provider or service Angular 6.

What are Tree shakeable providers in Angular 6?

In an earlier version of Angular, we need to register service or provider under provider sections of your module like below.

Now with Angular 6, There is recommended a way to register a provider or service in Angular directly inside the @Injectable decorator using new providedIn attribute. It accepts ‘root’ as a value or any module of your application. When you use ‘root’ your services or providers will be registered as a singleton and you don’t need to add that provider or service in the module. Same way if you add module instead of ‘root’ it will act as a singleton on your module.

This is how its look like now.

This is the new way of registering provider or service. This led us to better tree shaking in the application. What was happening in an earlier version of angular is If you add a service in providers list it will finally be added in bungle which is created at the end. Even if it not used in the application which is sad and can increase your size of the bundle. Most of the time we don’t add services in the application which we are not going to use But when you use third-party services it provides a list of services and we want only a few. So new smart Angular 6 compiler add only those services in the bundle which is actually being used.

Demo:

Now let’s create an application and see how it looks like. So I’m going to create an Angular6Provider app with Angular CLI like following.

create-new-angular6-app-providers

Once we are done with creating angular 6 application we are going to create a new service called “MessageService” like following.

create-angular6-service-provider

And following is the code I’ve written for printing a simple message.



Here in the above code, you can see that I have created a method called ‘printMessage’ and I am returning a simple observable of the string as a message. Please do notice that providerIn attribute in injector decorator.

Now let’s write some code in ‘app’ component to get the message from service. Following is a code I have written for that.
Here in the above code, You can see that I have injected the message service in the constructor of the component and then I have created a ‘printMessage’ method to get a message from our message service. Now let’s print this message in HTML part of app component like below.

Here you can see I have just printed a message via two curly braces. Now let’s run this application and with ng serve command and here is output in the browser as expected.

angular-6-provider-service

That’s it. Hope you like it. Stay tuned for more!!.

A minimal web application structure with technologies like node.js, typescript, express

Recently, I have been working the lot with Node.js and TypeScript. And I absolutely love TypeScript due to its features. I was actually looking for a boilerplate code to start which should be very easy to understand. But there was no code there. So I decided to create a minimum web application structure. I have used it in some project and I was quite happy with it.

So I thought why should I make it open source so that people can also get benefited by this. So here I am presenting A minimal Web Application Structure with technologies like Node.js, TypeScript, and Express.

You can find the complete source code on Github at following location - https://github.com/dotnetjalps/minimum-nodejs-typescript-express

How to Run this Project:

To run this project you need to first install all the NPM packages via the following command.
npm install 
Then you can run this project with the following command.
npm start

Directory Structure Of Project:

  • App.ts – Typescript file for creating express application class and where we have initialized the application.
  • routes.ts - Typescript files for creating all the routes under Init() Method.
  • package.json - Contains all the packages and dev dependencies required for this application. You can add more as your requirement.
  • tsconfig.json - Where all the typescript configuration is there and we converting typescript into ES5.
  • Controller Folder - Contains all the classes for the controller of the express application
  • tsconfig.josn  - Contains all the rules for TypeScript linting.
I’m looking for constructive feedback on this and I’m hoping that I will get it.

Video: How to debug Angular 5 application in Visual Studio Code with Chrome Debugger

Recently, I have been enjoying creating videos, So I have created a video related debugging of the Angular app in Visual Studio Code. In this video, I have shown how we can debug Angular 5 application in Visual Studio Code with Chrome Debugger Plugin and what configuration we need to make. And It always has a great feeling when you debug your application in the code editor itself instead of the browser.

You can install Chrome Debugger installer from here -

Flexible Object Mapping in Entity Framework Core 2.0

Entity Framework 2.0 is out for some time. If you don’t know Entity Framework 2.0 is a lightweight, extensible and Cross-Platform Object-relational mapper from Microsoft. It is a new version of Entity Framework which is now cross-platform and can now run now operating system like Linux, Mac etc.With Entity Framework Core 2.0, There are tons of ways to create a table and we are going to see one of that. In this blog post, We are going to see how we are going to see how we can create a field for private fields in the table.

So what we are waiting for. Let’s get started.

Flexible Object Mapping in Entity Framework Core 2.0:

So in this example, We are going to create a Console Application like following.

new-project-entity-framework-core

Once we are done with Creating Application We are going to insert NuGet Package for EF Core like below.

nuget-package-entity-framework-core

You can also install it via running following command.
Install-Package Microsoft.EntityFrameworkCore -Version 2.0.2
Here we are going to install SQL Server Express as a database so we need to install Nuget Package for that also.

enttity-framework-core-sqlserver-nuget-package

You can also install via running following command.
Install-Package Microsoft.EntityFrameworkCore.SqlServer -Version 2.0.2
Now it’s time to write some code. First of all, We are going to create A model called Student and In that, we are going to have two private fields.
namespace EFCore2Mapping
{
    public class Student
    {

        public int StudentId { get; set; }
        public string FirstName { get; set; }
        public string LastName { get; set; }


        private string _standard;
        private string _division;


        public void AssignStandard(string standard)
        {
            _standard = standard;
        }

        public void AssignDivision(string division)
        {
            _division = division;
        }

        public string GetStandard()
        {
            return _standard;
        }

        public string GetDivision()
        {
            return _division;
        }
    }
}

Here in the above code, You have seen that I have created few fields for Student Model. If you see it carefully, You can see that there are two private fields _standard and _division.  And there are two methods for each field to get and set private variables.

Now let’s write our Entity Framework Data Context. That’s where the Magic going to happen.
using Microsoft.EntityFrameworkCore;

namespace EFCore2Mapping
{
    public class StudentContext : DbContext
    {
        public DbSet<Student> Student { get; set; }
        protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
        {
            optionsBuilder.UseSqlServer("Data Source=Your Server;Initial Catalog=Student;User ID=sa;[email protected]");
        }

        protected override void OnModelCreating(ModelBuilder modelBuilder)
        {
            modelBuilder.Entity<Student>().Property<string>("Division").HasField("_division");
            modelBuilder.Entity<Student>().Property<string>("Standard").HasField("_standard");
        }
    }
}

Here in the above code, If you see I have created a dataset for our student model that is a standard way to create a table for the map. There is another method OnCofiguring for giving database connection string. There are is another method called OnModelCreating which Entity framework core uses to create tables. Here If you see that I have written code to map private fields to Table Fields so that two fields Division and Standard will be created with tables.

Now let’s run the migration to create a table like following.

migration-to-create-private-fields-in-table-entity-framework-core

You need to go to the Nuget Package Manager Console and then run the following command.
Add Migration Initial Create
Once you are done with it. It will create the tables in the database like following.

fields-created-in-SQL-Server

Now let’s write some code insert data in the table. So following is code for the same.
using System;
using System.Collections.Generic;
using System.Linq;

namespace EFCore2Mapping
{
    class Program
    {
        static void Main(string[] args)
        {

            List<Student> ExistingStudents = new List<Student>();

            Student student = new Student
            {
                FirstName = "Joe",
                LastName = "Tailor",
            };
            student.AssignStandard("5");
            student.AssignDivision("A");

            using (StudentContext studentConext = new StudentContext())
            {
                ///Adding a new Student;
                studentConext.Student.Add(student);
                studentConext.SaveChanges();


                ///Retriviting newly added student
                ExistingStudents = studentConext.Student.ToList();
                
            }

            foreach(Student s in ExistingStudents)
            {
                Console.WriteLine($"Student Id: {s.StudentId}");
                Console.WriteLine($"First Name: {s.FirstName}");
                Console.WriteLine($"Last Name:{s.LastName}");
                Console.WriteLine($"Standard:{s.GetStandard()}");
                Console.WriteLine($"Division:{s.GetDivision()}");
            }
        }
    }
}

Here you can see that in the above code, I have created Student called Joe Tailor and then I have saved it in the database and then I have written the code for fetching the student data and print it via for loop.

When you run this application It will show like following.

output-entity-framework-core-flexible-column-mapping

That’s it. Here you can see that It’s very easy to Manipulate the Columns with Entity Framework core 2.0. Hope you like it.

Solution: (Error)Unable to Correct problems, You have held broken packages–Install .NET Core on Ubuntu

Recently, I have been using Linux(Ubuntu) machine on my virtual box quite a bit and as  Microsoft.NET Developer I want to install .NET Core on Ubuntu. So I tried following the instruction from below link to install .NET core on Ubuntu 16.04.

https://docs.microsoft.com/en-us/dotnet/core/linux-prerequisites?tabs=netcore2x

But I was not unable to install .NET Core and I was getting following errors.

The following packages have unmet dependencies:
  dotnet-sdk-2.1.4 : Depends: dotnet-runtime-2.0.5 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
You can see the same error in the following screenshot.

error-ubuntu-net-core-214

I was a little bit curious about that and then I have read carefully the documentation mentioned on the above link and I have found that .NET Core require following require following Ubuntu distributions as Prerequisites.

  • libunwind8
  • liblttng-ust0
  • libcurl3
  • libssl1.0.0
  • libuuid1
  • libkrb5-3
  • zlib1g
  • libicu52 (for 14.X)
  • libicu55 (for 16.X)
  • libicu57 (for 17.X)

Most of the time it should be installed by default with sudo apt-get update and sudo apt-get upgrade command but sometimes it does not. So what I did install all these distributions one by one via sudo apt-get install command and in my case, I was not having liblttng-ust0 distribution on my machine. So I have installed it via the following command.

sudo apt-get install liblttng-ust0
You can also see below screenshot for the same.

install-ubuntu-distribution-for-netcore

Then I was able to install .NET Core on my machine via following above link on documentation.

install-netcore-ubuntu

And now it’s running .NET Core v 2.1.4 on my Ubuntu VirtualBox as you can see it in below dotnet version command.

net-core-version-command

I was able to solve my problem this and so I thought it will be a good idea to share it on my blog so it will help people who are having the same problem.

Stay tuned for more there is a lot more coming for asp.net core and node.js on Linux on future blog posts.

How to install Robo3T(Formerly RobMongo) on Ubuntu

Robo3T formerly known as RobMongo is one of best GUI tools for the managing and querying MongoDB database. I have been using it quite often for creating applications with MongoDB and Node.js. Recently a new version made available but there were no instructions for installing it on Ubuntu. So I thought it would be a great idea to write a blog post about it.

To install it. First, we need to open terminal and download tar.gz file from official site with the following command.
wget https://download.robomongo.org/1.2.1/linux/robo3t-1.2.1-linux-x86_64-3e50a65.tar.gz
robo3t-install-download-ubuntu

Once download will complete we need to extract tar.gz file with following command
tar -xvzf robo3t-1.2.1-linux-x86_64-3e50a65.tar.gz
extract-tar-file-robo3t-robmongo-ubuntu

As now we have extract it into the folder we need to move that under /usr/local/bin directory to make it available for all the users. So todo that we need to first create robo3t directly under /usr/local/bin folder with following command.
sudo mkdir /usr/local/bin/robo3t
mkdir-robo3t-robmongo-ubuntu

Then we need to move all the files of extracted folder into robo3t folder under /usr/local/bin directory with following command.
sudo mv  robo3t-1.2.1-linux-x86_64-3e50a65/* /usr/local/bin/robo3t
move-content-to-robo35-ubuntu

Now, We need to give permission to newly created directory with following command.
sudo chmod +x robo3t ./robo3t
permission-robo3t-robmongo-ubuntu

Once you are done with it. You are ready to use robo3t. You can run it from command line from usr/local/bin directory via following command.
./robo3t
run-robo35-command-line

And it will run the Robo3t like following.

robo3t-on-ubuntu

That’s it. Hope you like, Stay tuned for more!!.

How to install Visual Studio code on Ubuntu

Recently I presented a Webinar on ASP.NET Core on Linux. Here I have displayed how we can use Visual Studio Code a Free Open Source Editor from Microsoft to develop application. One of frequently ask question was How I can install Visual Studio Code on Linux. Since lots of People are using Ubuntu as Development Machine I thought it will be a good idea to write a blog post about how to install Visual Studio code on Linux(Ubuntu Machine).

So first thing we need to do it open a terminal in Ubuntu and then we need to type following command one by one.
curl https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > microsoft.gpg
Install-Visual-Studio-Code-Ubuntu

Then you need to run the following command to move gpg file download via Curl to etc/apt folder.
sudo mv microsoft.gpg /etc/apt/trusted.gpg.d/microsoft.gpg
Install-Visual-Studio-Code-Ubuntu2-move-folder

Now, You need to run following command.
sudo sh -c 'echo "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list'
package-cache-insert-vscode-ubuntu-linux

After that, you need to run Apt-get Command to update package cache and Apt-get install command to install visual studio code.
sudo apt-get update
sudo apt-get install code
pakcage-install-visual-studio-code

That’s it. You are done with installing Visual Studio Code. You can find more information about different Linux flavors at following  link on Visual Studio code.

From its powerful internal structure, fast performance, and reliability, SQL server is now widely accessed by several enterprise users. It is used to deal with bulk transaction processing, business programs, and content management. The Microsoft SQL server is chosen for its high-level security, scalability, and performance. Sometimes, corruption in the SQL database occurs due to the saving of a large amount of business information. This problem makes the server inaccessible, flashing an error message on the window.

One such message is ‘SQL server error 3403’, resulting in an unplanned downtime of the server.

Reason for SQL Server Error 3403:

Corruption and the server crash these two are the most common and root causes of the problem. Once the server crash takes place, the database verifies the transaction log. But, if the provided information does not match Object ID then, the application throws an error code 3403. It is possible that instead of these reasons there is some other cause of the problem. Following are those additional causes of SQL server error 3403 :
  • While updating the allocation page, the data gets written on the transaction log before the crashing takes place.
  • Another cause of the problem might be bad allocation activity by Microsoft SQL server.

The best way to deal with any of the SQL server error (including 3403) is to restore data from the recently created backup file. If you are having the backup file then, you just need to perform following steps :

  • It’s time to restore database file and utilize online commands for activating restored files for use.
Note: Verify that the database files created at present must be having same size as of Sysusages value.

Alternative Solution to Fix SQL Server Error 3403:
